Most satellites they tell us are orbiting the earth. Well obviously the satellite dish on your house couldn't be pointing to any of them or you'd lose signal constantly, especially when the satellite you were pointing at around noon is on the other side of the earth hours later. So what we are told they are pointing at is a Satellite 22,236 miles away, and it's traveling at 6,935 mph to maintain a perfectly synchronous orbit with the 1,040 mph spin of the earth.
https://en.wikipedia.org/wiki/Geostationary_orbit
First of all, do you really think Mr Dish network can hit something at over 22 thousand miles away? :) Now this is pure crazy no matter how you look at it, cause that means the ISS that's 249 miles away isn't locked in to earths spin and it's actually traveling around the earth at over 17,150 mph. Yet at 22,236 miles away these satellites are caught in the spin of the earth??
The Van Allen belt would pose a problem, the inner belt is from 620mi - 3,700mi and the outer belt is from 8,100mi - 37,300mi.
https://en.wikipedia.org/wiki/Van_Allen_radiation_belt Hope this video helped some see the ridiculousness we have been taught, God Bless!
"For nothing is hidden which will not become manifest, nor secret which shall not be known and come to light. " Luke 8:17
Getting saved is the easiest and most important thing you can do :) You just have to come to the knowledge that you (like everyone else on earth) are a sinner in need of salvation or we would spend eternity in Hell. Salvation is not something we could ever attain on our own, that is why Jesus came to this earth and paid the ultimate price for our sins by allowing himself to be sacrificed for all mankind so through him we can be saved. Jesus led a sinless life and by doing so was able to take all of humanities sins they would ever commit on himself making one sacrifice that covered all sin.
To be saved you have to say a prayer something like this (and most importantly mean it because God reads your heart). Say "God I know I am a sinner. I know that because of my sin Jesus came to this earth and died for me making atonement for all the sins I would ever commit. I believe Jesus died on that cross and raised from the dead three days later conquering death and making a way for me to be saved by taking my sins upon himself. I pray Lord that you save me and come into my heart and life allowing me to be born again through Jesus, living in this world but no longer being of this world. Thank you Lord for saving my soul please lead me, guide me, and direct me all the remaining days of my life. In Jesus name I pray, Amen."
If you said that prayer and meant it you are saved and sealed and nothing anyone could ever say or do can take that away. I would continue to pray daily building a relationship with God, and read the bible some everyday as well. He knows you, but that's the only way to get to know him. Try your best to stop sinning (this is not possible by the way) but you have to make the effort because that is what true repentance means is that you will turn from your sin. Don't give up, this is not easy, I repent and ask God to forgive me for something or another every single day. He knows we aren't perfect, but if we truly love him we gotta try :)
God bless you, here are some scriptures that you might find helpful, and welcome to the family! :D
John3:3 (KJV) 3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Romans 3:23 (KJV) 23 For all have sinned, and come short of the glory of God;
Romans 6:23 (KJV) 23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Romans 5:8 (KJV) 8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Romans 10:9-10 (KJV) 9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Romans 10:13 (KJV) 13 For whosoever shall call upon the name of the Lord shall be saved.
John 3:16-17 (KJV) 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.

SatelliteCommunication
A satellite is an artificial body placed in an orbit around the earth or another planet.
The communication satellites relay around the world, telephone and fax messages, television programmes, radio signals and so on.
Principle of satellite communication
The process of communication begins at an earth station.
The earth station is an Installation designed to transmit and receive signals from a satellite in orbit around the earth.
Earth stations and information in the form of high powered high frequency signals to satellites that receive and retransmit the signals back to earth.
These retransmitted signals are then received by other earth stations in the coverage area of the satellite.
The area which receives the signal from the satellite is known as the satellite’s footprint.
The transmission system from the earth station to the satellite is called the up link and the transmission system from the satellite to the earth station is called the down link.
Here you have the schematic representation of the principle of satellite communication
To avoid confusion, the uplink and down link frequencies are kept different.
Before designing a satellite communication system, we must choose the orbit in which the satellite is to be placed.
Orbits are of three types namely geostationary orbit or geosynchronous orbit, polar circular orbit and inclined highly elliptical orbit.
Geostationary or geosynchronous orbit
In this type of orbit, the satellite takes twenty four hours to circle once around the earth.
Since the period of revolution of the satellite is equal to the period of rotation of the earth, the satellite appears to be stationary in the sky. For this reason, this thirty five thousands nine hundred kilometers high equatorial orbit is called a geostationary orbit.
The geostationary orbit is also known as Clarke’s orbit. This is in honor of Arthur C. Clarke, the man who first suggested in 1945 that satellites in geosynchronous orbit could be used for communication purposes.
Entire earth can be linked or covered by the communication network if three geostationary satellites are placed at the vertices of an equilateral triangle.
Each of the satellite covers one third of the globe.
PolarCircular Orbit
This type of orbit is placed thousand kilometers above earth’s surface. It passes over the poles. The angle of inclination of this orbit is ninety degrees.
It scans the whole earth in every twelve hours.
Satellites used for weather monitoring are launched into a polar orbit.
Inclined highly elliptical orbit
It is used for establishing communication with regions at high latitudes.
The angle of inclination is equal to sixty three degrees.

What isLOWEARTH ORBIT? What does LOW EARTH ORBIT mean? LOW EARTH ORBIT meaning - LOW EARTH ORBIT definition - LOW EARTH ORBIT explanation.
Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.
A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 kilometers (99 mi) (orbital period of about 88 minutes), and 2,000 kilometers (1,200 mi) (about 127 minutes). Objects below approximately 160 kilometers (99 mi) will experience very rapid orbital decay and altitude loss. The orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude.
With the exception of the manned lunar flights of the Apollo program, all human spaceflights have taken place in LEO (or were suborbital). The International Space Station conducts operations in LEO. The altitude record for a human spaceflight in LEO was Gemini 11 with an apogee of 1,374.1 kilometers (853.8 mi). All manned space stations to date, as well as the majority of satellites, have been in LEO.
Objects in LEO encounter atmospheric drag from gases in the thermosphere (approximately 80–500 km up) or exosphere (approximately 500 km and up), depending on orbit height. Due to atmospheric drag, satellites do not usually orbit below 300 km. Objects in LEO orbit Earth between the denser part of the atmosphere and below the inner Van Allen radiation belt.
The orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude. Calculated for circular orbit of 200 km it is 7.79 km/s and for 1500 km it is 7.12 km/s. The delta-v needed to achieve low Earth orbit starts around 9.4 km/s. Atmospheric and gravity drag associated with launch typically adds 1.3–1.8 km/s to the launch vehicle delta-v required to reach normal LEO orbital velocity of around 7.8 km/s (28,080 km/h).
Equatorial low Earth orbits (ELEO) are a subset of LEO. These orbits, with low inclination to the Equator, allow rapid revisit times and have the lowest delta-v requirement (i.e., fuel spend) of any orbit. Orbits with a high inclination angle to the equator are usually called polar orbits.
Higher orbits include medium Earth orbit (MEO), sometimes called intermediate circular orbit (ICO), and further above, geostationary orbit (GEO). Orbits higher than low orbit can lead to early failure of electronic components due to intense radiation and charge accumulation.
Although the Earth's pull due to gravity in LEO is not much less than on the surface of the Earth, people and objects in orbit experience weightlessness because they are in free fall.
A low Earth orbit is simplest and cheapest for satellite placement. It provides high bandwidth and low communication time lag (latency), but satellites in LEO will not be visible from any given point on the Earth at all times.

Geostationary orbit

A geostationary orbit, geostationary Earth orbit or geosynchronous equatorial orbit (GEO) is a circular orbit35,786 kilometres (22,236mi) above the Earth's equator and following the direction of the Earth's rotation. An object in such an orbit has an orbital period equal to the Earth's rotational period (one sidereal day), and thus appears motionless, at a fixed position in the sky, to ground observers. Communications satellites and weather satellites are often placed in geostationary orbits, so that the satellite antennas (located on earth) which communicate with them do not have to rotate to track them, but can be pointed permanently at the position in the sky where the satellites are located. Using this characteristic, ocean color satellites with visible and near-infrared light sensors (e.g. the Geostationary Ocean Color Imager (GOCI)) can also be operated in geostationary orbit in order to monitor sensitive changes of ocean environments.

A geostationary orbit is a particular type of geosynchronous orbit, the distinction being that while an object in geosynchronous orbit returns to the same point in the sky at the same time each day, an object in geostationary orbit never leaves that position.

Geostationary and Polar Satellites

Astra geostationary satellites through telescope

This video shows various Astra geostationary satellites moving along their orbital paths. Two clusters (constellations) consisting of 5 and respectively 6 satellites can be seen as well as a lone sat undergoing an eclipse.
The satellites featured in the video are Astra 1F, 1G, 1H, 1KR, 1L, 1M, and 2C.
All the images and videos were recorded using a 150mm (6") f/5 telescope and a Canon 350DDSLR.

Satellites Do Not Exist - Flat Earth

Most satellites they tell us are orbiting the earth. Well obviously the satellite dish on your house couldn't be pointing to any of them or you'd lose signal constantly, especially when the satellite you were pointing at around noon is on the other side of the earth hours later. So what we are told they are pointing at is a Satellite 22,236 miles away, and it's traveling at 6,935 mph to maintain a perfectly synchronous orbit with the 1,040 mph spin of the earth.
https://en.wikipedia.org/wiki/Geostationary_orbit
First of all, do you really think Mr Dish network can hit something at over 22 thousand miles away? :) Now this is pure crazy no matter how you look at it, cause that means the ISS that's 249 miles away isn't locked in to earths spin and it's actually traveling around the earth a...

Understand Satellite Communication

SatelliteCommunication
A satellite is an artificial body placed in an orbit around the earth or another planet.
The communication satellites relay around the world, telephone and fax messages, television programmes, radio signals and so on.
Principle of satellite communication
The process of communication begins at an earth station.
The earth station is an Installation designed to transmit and receive signals from a satellite in orbit around the earth.
Earth stations and information in the form of high powered high frequency signals to satellites that receive and retransmit the signals back to earth.
These retransmitted signals are then received by other earth stations in the coverage area of the satellite.
The area which receives the signal from the satellite is known as the satellite’s ...

Most satellites they tell us are orbiting the earth. Well obviously the satellite dish on your house couldn't be pointing to any of them or you'd lose signal constantly, especially when the satellite you were pointing at around noon is on the other side of the earth hours later. So what we are told they are pointing at is a Satellite 22,236 miles away, and it's traveling at 6,935 mph to maintain a perfectly synchronous orbit with the 1,040 mph spin of the earth.
https://en.wikipedia.org/wiki/Geostationary_orbit
First of all, do you really think Mr Dish network can hit something at over 22 thousand miles away? :) Now this is pure crazy no matter how you look at it, cause that means the ISS that's 249 miles away isn't locked in to earths spin and it's actually traveling around the earth at over 17,150 mph. Yet at 22,236 miles away these satellites are caught in the spin of the earth??
The Van Allen belt would pose a problem, the inner belt is from 620mi - 3,700mi and the outer belt is from 8,100mi - 37,300mi.
https://en.wikipedia.org/wiki/Van_Allen_radiation_belt Hope this video helped some see the ridiculousness we have been taught, God Bless!
"For nothing is hidden which will not become manifest, nor secret which shall not be known and come to light. " Luke 8:17
Getting saved is the easiest and most important thing you can do :) You just have to come to the knowledge that you (like everyone else on earth) are a sinner in need of salvation or we would spend eternity in Hell. Salvation is not something we could ever attain on our own, that is why Jesus came to this earth and paid the ultimate price for our sins by allowing himself to be sacrificed for all mankind so through him we can be saved. Jesus led a sinless life and by doing so was able to take all of humanities sins they would ever commit on himself making one sacrifice that covered all sin.
To be saved you have to say a prayer something like this (and most importantly mean it because God reads your heart). Say "God I know I am a sinner. I know that because of my sin Jesus came to this earth and died for me making atonement for all the sins I would ever commit. I believe Jesus died on that cross and raised from the dead three days later conquering death and making a way for me to be saved by taking my sins upon himself. I pray Lord that you save me and come into my heart and life allowing me to be born again through Jesus, living in this world but no longer being of this world. Thank you Lord for saving my soul please lead me, guide me, and direct me all the remaining days of my life. In Jesus name I pray, Amen."
If you said that prayer and meant it you are saved and sealed and nothing anyone could ever say or do can take that away. I would continue to pray daily building a relationship with God, and read the bible some everyday as well. He knows you, but that's the only way to get to know him. Try your best to stop sinning (this is not possible by the way) but you have to make the effort because that is what true repentance means is that you will turn from your sin. Don't give up, this is not easy, I repent and ask God to forgive me for something or another every single day. He knows we aren't perfect, but if we truly love him we gotta try :)
God bless you, here are some scriptures that you might find helpful, and welcome to the family! :D
John3:3 (KJV) 3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Romans 3:23 (KJV) 23 For all have sinned, and come short of the glory of God;
Romans 6:23 (KJV) 23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Romans 5:8 (KJV) 8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Romans 10:9-10 (KJV) 9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Romans 10:13 (KJV) 13 For whosoever shall call upon the name of the Lord shall be saved.
John 3:16-17 (KJV) 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.

SatelliteCommunication
A satellite is an artificial body placed in an orbit around the earth or another planet.
The communication satellites relay around the world, telephone and fax messages, television programmes, radio signals and so on.
Principle of satellite communication
The process of communication begins at an earth station.
The earth station is an Installation designed to transmit and receive signals from a satellite in orbit around the earth.
Earth stations and information in the form of high powered high frequency signals to satellites that receive and retransmit the signals back to earth.
These retransmitted signals are then received by other earth stations in the coverage area of the satellite.
The area which receives the signal from the satellite is known as the satellite’s footprint.
The transmission system from the earth station to the satellite is called the up link and the transmission system from the satellite to the earth station is called the down link.
Here you have the schematic representation of the principle of satellite communication
To avoid confusion, the uplink and down link frequencies are kept different.
Before designing a satellite communication system, we must choose the orbit in which the satellite is to be placed.
Orbits are of three types namely geostationary orbit or geosynchronous orbit, polar circular orbit and inclined highly elliptical orbit.
Geostationary or geosynchronous orbit
In this type of orbit, the satellite takes twenty four hours to circle once around the earth.
Since the period of revolution of the satellite is equal to the period of rotation of the earth, the satellite appears to be stationary in the sky. For this reason, this thirty five thousands nine hundred kilometers high equatorial orbit is called a geostationary orbit.
The geostationary orbit is also known as Clarke’s orbit. This is in honor of Arthur C. Clarke, the man who first suggested in 1945 that satellites in geosynchronous orbit could be used for communication purposes.
Entire earth can be linked or covered by the communication network if three geostationary satellites are placed at the vertices of an equilateral triangle.
Each of the satellite covers one third of the globe.
PolarCircular Orbit
This type of orbit is placed thousand kilometers above earth’s surface. It passes over the poles. The angle of inclination of this orbit is ninety degrees.
It scans the whole earth in every twelve hours.
Satellites used for weather monitoring are launched into a polar orbit.
Inclined highly elliptical orbit
It is used for establishing communication with regions at high latitudes.
The angle of inclination is equal to sixty three degrees.

What isLOWEARTH ORBIT? What does LOW EARTH ORBIT mean? LOW EARTH ORBIT meaning - LOW EARTH ORBIT definition - LOW EARTH ORBIT explanation.

A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 kilometers (99 mi) (orbital period of about 88 minutes), and 2,000 kilometers (1,200 mi) (about 127 minutes). Objects below approximately 160 kilometers (99 mi) will experience very rapid orbital decay and altitude loss. The orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude.
With the exception of the manned lunar flights of the Apollo program, all human spaceflights have taken place in LEO (or were suborbital). The International Space Station conducts operations in LEO. The altitude record for a human spaceflight in LEO was Gemini 11 with an apogee of 1,374.1 kilometers (853.8 mi). All manned space stations to date, as well as the majority of satellites, have been in LEO.
Objects in LEO encounter atmospheric drag from gases in the thermosphere (approximately 80–500 km up) or exosphere (approximately 500 km and up), depending on orbit height. Due to atmospheric drag, satellites do not usually orbit below 300 km. Objects in LEO orbit Earth between the denser part of the atmosphere and below the inner Van Allen radiation belt.
The orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude. Calculated for circular orbit of 200 km it is 7.79 km/s and for 1500 km it is 7.12 km/s. The delta-v needed to achieve low Earth orbit starts around 9.4 km/s. Atmospheric and gravity drag associated with launch typically adds 1.3–1.8 km/s to the launch vehicle delta-v required to reach normal LEO orbital velocity of around 7.8 km/s (28,080 km/h).
Equatorial low Earth orbits (ELEO) are a subset of LEO. These orbits, with low inclination to the Equator, allow rapid revisit times and have the lowest delta-v requirement (i.e., fuel spend) of any orbit. Orbits with a high inclination angle to the equator are usually called polar orbits.
Higher orbits include medium Earth orbit (MEO), sometimes called intermediate circular orbit (ICO), and further above, geostationary orbit (GEO). Orbits higher than low orbit can lead to early failure of electronic components due to intense radiation and charge accumulation.
Although the Earth's pull due to gravity in LEO is not much less than on the surface of the Earth, people and objects in orbit experience weightlessness because they are in free fall.
A low Earth orbit is simplest and cheapest for satellite placement. It provides high bandwidth and low communication time lag (latency), but satellites in LEO will not be visible from any given point on the Earth at all times.

Calculated for circular orbit of 200 km it is 7.79 km/s and for 1500 km it is 7.12 km/s. The delta-v needed to achieve low Earth orbit starts around 9.4 km/s. Atmospheric and gravity drag associated with launch typically adds 1.3–1.8 km/s to the launch vehicle delta-v required to reach normal LEO orbital velocity of around 7.8 km/s (28,080 km/h).
Equatorial low Earth orbits (ELEO) are a subset of LEO. These orbits, with low inclination to the Equator, allow rapid revisit times and have the lowest delta-v requirement (i.e., fuel spend) of any orbit. Orbits with a high inclination angle to the equator are usually called polar orbits.
Higher orbits include medium Earth orbit (MEO), sometimes called intermediate circular orbit (ICO), and further above, geostationary orbit (GEO). Orbits higher than low orbit can lead to early failure of electronic components due to intense radiation and charge accumulation.
Although the Earth's pull due to gravity in LEO is not much less than on the surface of the Earth, people and objects in orbit experience weightlessness because they are in free fall.
A low Earth orbit is simplest and cheapest for satellite placement. It provides high bandwidth and low communication time lag (latency), but satellites in LEO will not be visible from any given point on the Earth at all times.

Satellites Do Not Exist - Flat Earth

Most satellites they tell us are orbiting the earth. Well obviously the satellite dish on your house couldn't be pointing to any of them or you'd lose signal constantly, especially when the satellite you were pointing at around noon is on the other side of the earth hours later. So what we are told they are pointing at is a Satellite 22,236 miles away, and it's traveling at 6,935 mph to maintain a perfectly synchronous orbit with the 1,040 mph spin of the earth.
https://en.wikipedia.org/wiki/Geostationary_orbit
First of all, do you really think Mr Dish network can hit something at over 22 thousand miles away? :) Now this is pure crazy no matter how you look at it, cause that means the ISS that's 249 miles away isn't locked in to earths spin and it's actually traveling around the earth at over 17,150 mph. Yet at 22,236 miles away these satellites are caught in the spin of the earth??
The Van Allen belt would pose a problem, the inner belt is from 620mi - 3,700mi and the outer belt is from 8,100mi - 37,300mi.
https://en.wikipedia.org/wiki/Van_Allen_radiation_belt Hope this video helped some see the ridiculousness we have been taught, God Bless!
"For nothing is hidden which will not become manifest, nor secret which shall not be known and come to light. " Luke 8:17
Getting saved is the easiest and most important thing you can do :) You just have to come to the knowledge that you (like everyone else on earth) are a sinner in need of salvation or we would spend eternity in Hell. Salvation is not something we could ever attain on our own, that is why Jesus came to this earth and paid the ultimate price for our sins by allowing himself to be sacrificed for all mankind so through him we can be saved. Jesus led a sinless life and by doing so was able to take all of humanities sins they would ever commit on himself making one sacrifice that covered all sin.
To be saved you have to say a prayer something like this (and most importantly mean it because God reads your heart). Say "God I know I am a sinner. I know that because of my sin Jesus came to this earth and died for me making atonement for all the sins I would ever commit. I believe Jesus died on that cross and raised from the dead three days later conquering death and making a way for me to be saved by taking my sins upon himself. I pray Lord that you save me and come into my heart and life allowing me to be born again through Jesus, living in this world but no longer being of this world. Thank you Lord for saving my soul please lead me, guide me, and direct me all the remaining days of my life. In Jesus name I pray, Amen."
If you said that prayer and meant it you are saved and sealed and nothing anyone could ever say or do can take that away. I would continue to pray daily building a relationship with God, and read the bible some everyday as well. He knows you, but that's the only way to get to know him. Try your best to stop sinning (this is not possible by the way) but you have to make the effort because that is what true repentance means is that you will turn from your sin. Don't give up, this is not easy, I repent and ask God to forgive me for something or another every single day. He knows we aren't perfect, but if we truly love him we gotta try :)
God bless you, here are some scriptures that you might find helpful, and welcome to the family! :D
John3:3 (KJV) 3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Romans 3:23 (KJV) 23 For all have sinned, and come short of the glory of God;
Romans 6:23 (KJV) 23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Romans 5:8 (KJV) 8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Romans 10:9-10 (KJV) 9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Romans 10:13 (KJV) 13 For whosoever shall call upon the name of the Lord shall be saved.
John 3:16-17 (KJV) 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.

Understand Satellite Communication

SatelliteCommunication
A satellite is an artificial body placed in an orbit around the earth or another planet.
The communication satellites relay around the world, telephone and fax messages, television programmes, radio signals and so on.
Principle of satellite communication
The process of communication begins at an earth station.
The earth station is an Installation designed to transmit and receive signals from a satellite in orbit around the earth.
Earth stations and information in the form of high powered high frequency signals to satellites that receive and retransmit the signals back to earth.
These retransmitted signals are then received by other earth stations in the coverage area of the satellite.
The area which receives the signal from the satellite is known as the satellite’s footprint.
The transmission system from the earth station to the satellite is called the up link and the transmission system from the satellite to the earth station is called the down link.
Here you have the schematic representation of the principle of satellite communication
To avoid confusion, the uplink and down link frequencies are kept different.
Before designing a satellite communication system, we must choose the orbit in which the satellite is to be placed.
Orbits are of three types namely geostationary orbit or geosynchronous orbit, polar circular orbit and inclined highly elliptical orbit.
Geostationary or geosynchronous orbit
In this type of orbit, the satellite takes twenty four hours to circle once around the earth.
Since the period of revolution of the satellite is equal to the period of rotation of the earth, the satellite appears to be stationary in the sky. For this reason, this thirty five thousands nine hundred kilometers high equatorial orbit is called a geostationary orbit.
The geostationary orbit is also known as Clarke’s orbit. This is in honor of Arthur C. Clarke, the man who first suggested in 1945 that satellites in geosynchronous orbit could be used for communication purposes.
Entire earth can be linked or covered by the communication network if three geostationary satellites are placed at the vertices of an equilateral triangle.
Each of the satellite covers one third of the globe.
PolarCircular Orbit
This type of orbit is placed thousand kilometers above earth’s surface. It passes over the poles. The angle of inclination of this orbit is ninety degrees.
It scans the whole earth in every twelve hours.
Satellites used for weather monitoring are launched into a polar orbit.
Inclined highly elliptical orbit
It is used for establishing communication with regions at high latitudes.
The angle of inclination is equal to sixty three degrees.

What isLOWEARTH ORBIT? What does LOW EARTH ORBIT mean? LOW EARTH ORBIT meaning - LOW EARTH ORBIT definition - LOW EARTH ORBIT explanation.
Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.
A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 kilometers (99 mi) (orbital period of about 88 minutes), and 2,000 kilometers (1,200 mi) (about 127 minutes). Objects below approximately 160 kilometers (99 mi) will experience very rapid orbital decay and altitude loss. The orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude.
With the exception of the manned lunar flights of the Apollo program, all human spaceflights have taken place in LEO (or were suborbital). The International Space Station conducts operations in LEO. The altitude record for a human spaceflight in LEO was Gemini 11 with an apogee of 1,374.1 kilometers (853.8 mi). All manned space stations to date, as well as the majority of satellites, have been in LEO.
Objects in LEO encounter atmospheric drag from gases in the thermosphere (approximately 80–500 km up) or exosphere (approximately 500 km and up), depending on orbit height. Due to atmospheric drag, satellites do not usually orbit below 300 km. Objects in LEO orbit Earth between the denser part of the atmosphere and below the inner Van Allen radiation belt.
The orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude. Calculated for circular orbit of 200 km it is 7.79 km/s and for 1500 km it is 7.12 km/s. The delta-v needed to achieve low Earth orbit starts around 9.4 km/s. Atmospheric and gravity drag associated with launch typically adds 1.3–1.8 km/s to the launch vehicle delta-v required to reach normal LEO orbital velocity of around 7.8 km/s (28,080 km/h).
Equatorial low Earth orbits (ELEO) are a subset of LEO. These orbits, with low inclination to the Equator, allow rapid revisit times and have the lowest delta-v requirement (i.e., fuel spend) of any orbit. Orbits with a high inclination angle to the equator are usually called polar orbits.
